Improvement in hoeing-machine



' plows.

HORACE CVBRIGGS, 0F WEST AUBURN, Letters Patent No. 87,627, dated March 9, 1869.

` IIMPROVEMENT IN HOEING-MACHINE To all whom 'it may concern Be itknowu that I, HORACE 0. BRIees, of West Auburn, in the county ofAudroscoggin, and State of Maine, have invented a new and useful Improvement in Hoeing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art` to make and-use the same, referhce being had to the accompanying drawings, forming part of this specification, in which- Figure l is a'side view of my improved machine, partly in section, to show the construction.

Figure 2 is a .top or plan view ofthe same, parts Abeing broken away, to show the construction.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of my improved hoeing-machine, patented, November 17, 1868, and numbered 84,165, so as to make it more convenient and effective in use; and

It consists in the construction and combination of various partsof the machine, as hereinafter more fully described.

A is the fron't or longer cross-bar,

Bris the rear or shorter cross-bar;

Gare the adjustable longitudinal bars;

D are the'runners;

E are' the adjustable knees;

F are the adjustable brace-rods;

G are theY curved parts, -or pieces, formed upon or `attached to the horizontal parts of the runners; and

H arethe draught-irons.

All of these parts are constructed and combined in accordance with-patent, N o. 84,165.

I are theplows, which are made in about the form `shown in iigs. land 2, so as to cut up the weeds, stir and turn over the ground, moving the soil toward or from the plants, according to the adjustment of 'said The plcws I are formed with ears upon their upper edges, by means of which they are secured to the runners D, by bolts, passing', the one through eyes, at-

taclied to the outer' sidesof the runner D, and' the other passing through one or the other of the holes formed for it in the' said runners D, according as it is desired to turn the soil toward or from the plants.

In the case of the rear plowsL-both bolts pass through ears, attached to the inner sides of the rear ends of the runners D, as shown in iig. 2.

. J are inwardly-projecting hoes, the Shanks of which enter and are adjustablysecured, by Aset-screws,'in

grooves formed in caps, attached to the rear ends of the runners D, so' that the said hoes may be adjusted to throw'the soil more or less closely around the plants,

as may be desired.

K is the tongue, which is hinged to the lower part of the forward side of the front cross-bar A, and the play of which is limited by the slotted wedge-blocks L, which are adjustably secured to the forward side ofthe bar A, by bolts passing through said bar, or through keepers, or blocks M, attached thereto, and which support the upper ends of said wedges.

The pole ofthe tongue K is inclined to one side, and its rear end is strongly braced, to, adapt the maf chine for use with one horse. When two Yhorses are to be used, the tongue K should be straight.

AN is the draw-bar, which is made in three parts, the cent-ral part being pivoted to the tongue, and the end parts being connected with the draw-irons H.

The inner ends of the end parts of the draw-bar N are connected with the ends of the central part by short chains, as shown in vtig. 1, the draught being applied to the outer end of said end parts. v

This construction of the draw-bar protects the plants, while being cultivated, from any liability to be injured by the draught-bar. 'l

O is an axle, upon which work the wheels'E, and

which passes across the machine, above the runners D, and below the bars C, and' is connected with the frame of the machine by adjustable keepers, P, which pass around the central brace-rods F, and through slots in the said axle O, so that the frame of the machine may be conveniently raised and lowered upon the said axle, when desired.

To the upper side of the axle O, near its ends, are attached arms, Q, projecting forward, and having projections formed upon their. rear ends, directly over the 'aXle O, to which projections are pivoted the angles of the bent levers R, the long arms of which extend up into "such a position as to be conveniently reached and operated by the driver from his seat.-

Upon the end of the short arms of the bent levers R, are formed curved segments lr', having a groove upon their convex faces.

To the upper end of the segmental arms r are attached the upper ends ofthe chains S, the lower ends' of which are connected with the 'runners D, so that,

by operating the levers R, the entire frame-work of the machine maybe raised from the ground. When raisedl iomthe ground, the fram e-work of the machine is held suspended, by allowing the lower ends of the segmental arms fr to rest upon the forward ends of the armsQ, i

as shown in iig. 1.

The machine maybe used withl or withoutthe wheels and axle, and hoisting-device, if desired.

'I is a bar, having teeth formed upon its rear edge, andwhich bar slides longitudinally in a recess between two plates, U, attached to the under side of the middle part of the front cross-bar A.

To the under side of the ends of the bar T are attached, or upon them are formed, downward-projecting arms, V, to the lower ends'of which are attached `the upper ends of the standards W, to the lower ends hillsn To the rear side of the rear crossbar B are attached the upper ends of the arms A', and the lower ends of which are slotted, to receive the bolts by which the journal-boxesrB are secured in place, said journal-boxes B' being made with au angle or projection upon their in-l ner side, to enter one or the other of the notches formed in the rear sides of the lower ends of the arms A', as

shown in ng. 1.

The lower ends of the arms A may be connected with the rear ends of the runners D by short chains C. D is a roller, the journals of- Which work in the boxes B', as shown in rigs. and 2'.

The roller D is designed to be used when the machine is used as a planter, in which case a seedhopper may be attached to the frame of thel machine, and operated to drop the seed by any ot' the well-known means for that purpose.

When the machine is to be used as a cultivator, the roller D' and arms A should be detached.

Having thus describedl my invention, -I claim as neng,` and desire to secure by Letters Patentl. The combination of the axle O and wheels with the frame A B (l D E F of the cultivator, substantially as herein shown and described, and for the purpose set forth.

2. The combination of the arms and supports Q, le-

vers R fr', andchains S, with the axle O and runners D, substantially as herein shown and described, and for the/purpose set forth.'

.../3. The combination ofthe foot-lever Z, pivoted toothed plate Yftoothed bar T, arms V, standards W, and plows, or hoes X, with each other, and with the forward crossbar A of the cuitivatordrame, substantially as herein shown and described, and for the purpose set forth.

4. Forming the standards W' with tivo separate and distinct seats, for the plows, or hoes, substantially as herein shown and described, and for the purpose sety forth. v.

5. The draught-bar'N, constructed in three parts, and operating in connection with the tongue K and draueht-irons H, substantially as herein shown and described, and for the purpose set forth.

The combination of. the roller D and detachable arms A' Withtbe rear er0ss-bars B and runners D of the cnltivator-iame, substantially as herein shown and described, and for-the purpose set forth.

7, The combination of the adjustable wedge-block L with the forward cross-bar A and inclined rear end of the tongue, substantially as herein shown and de scribed, and for the purpose set forth.

The Iabove specification of my invention signed by me, this 11th day of January, 1869.
